The main purpose of this study is to characterize the high temperature deformation behavior of modified 5052 Al alloy through hot torsion test. Specimens were hot-worked by torsion test at temperature range from 573 K to 773 K and at the strain rates of 0.1/s - 10/s. Temperature rise during plastic deformation due to deformation heat was considered and the compensated flow curves were derived to estimate the hot deformation behavior of experimental Al alloy. Peak stress had a tendency to have large value on the condition of lower temperature and higher strain rate, which was an opposite result in comparison of effective strain. Obtained processing map of the experimental alloy noticed that the maximum power dissipation values were observed at 773K of minimum and maximum strain rate. Microstructure investigation was carried out to interpret the acquired result of processing map.
